|
|
Hello all,
I have been trying to install Gentoo on an EFI-enabled virtualbox for a few days, having failed a few times, and getting further with each next attempt. However, now I am truly stumped and I need some help.
I followed the bootloader section of the handbook and installed grub, then ran Code: | grub-install --target=x86_64-efi --efi-directory=/boot |
which failed at first, but worked after following the handbook's advice.
Then, I ran Code: | grub-mkconfig -o /boot/grub/grub.cfg |
which seemed happily accomplish it's task without any issue.
Next, the handbook instructs the reader to reboot and remove the installation media, which I did. Now my virtual machine boots into the UEFI shell and I am not sure how to proceed with troubleshooting.
I am determined to understand what I have done wrong, and to succeed at installing Gentoo. Any help is greatly appreciated.
My disk is set up like this:
/dev/sda1 is boot, vfat, 512 MB
/dev/sda2 is swap, 512 MB,
/dev/sda3 is root, ext4, 9 GB |

The disk partitioning layout is not incorrect but may need the proper boot flags sorted. that may explain why the efi shell is being launched instead of gentoo?
I was also going to say the partition layout looks familiar

check your bios boot order as well.
I dont see any obvious reasons why this should fail to boot based on the information offered however based on the information offered a couple general assumptions could be tested.
One assumption could be that your /boot/EFI mount for sda1 is incorrect. the path to this mount matters as some efi firmwares are dumb and don't obey best practice standards. _________________ Compiling Gentoo since version 1.4

VirtualBox VM keeps nvram hard coded so you can't modify EFI boot with efibootmgr. You have to rename or copy /boot/grubx64.efi --> /boot/bootx64.efi
You have to boot from CD like live CD or SystemRescueCD, do above step and reboot. |
